Description

Technical Field

[0001] This utility model relates to the field of pumpkin seed dust removal technology, specifically a negative pressure dust removal packaging and conveying machine for pumpkin seed production. Background Technology

[0002] During the production and processing of pumpkin seeds, a large amount of impurities are often generated during the harvesting process. Even after simple filtration, dust may still remain on the surface. To avoid this, the pumpkin seeds need to undergo negative pressure dust removal treatment before packaging. By using a negative pressure dust removal packaging conveyor, the pumpkin seeds can be transported from the inlet to the outlet, and dust can be adsorbed during the process.

[0003] Chinese Patent Publication No. CN213762778U discloses "A Negative Pressure Dust Removal Packaging and Conveying Machine for Pumpkin Seed Production," which includes a base. A housing is fixedly connected to the top outer wall of the base, and a motor is fixedly connected to one side outer wall of the housing. A cam is fixedly connected to one end of the output shaft of the motor, and fixed rods are fixedly connected to both sides of the bottom inner wall of the housing. A sieve plate is rotatably connected to the opposite side of the two fixed rods, and support plates are fixedly connected to both sides of one side inner wall of the housing. A spring is fixedly connected to the top outer wall of the support plate, and one end of the spring is fixedly connected to the bottom outer wall of the sieve plate. By providing a motor, the operation of the motor drives the rotation of the cam. The cam acts on the sieve plate, and under the action of the spring, the sieve plate swings around the fixed rods within a certain angle. In this way, impurities in the pumpkin seeds on the sieve plate are separated by the sieve holes, greatly improving the overall quality of the product.

[0004] In existing technologies, pumpkin seeds typically require filtration before dust removal. However, dust still remains during the filtration process. The existing dust removal structure is located close to the vibration zone, causing dust to float and cover other internal structures, making it impossible to adsorb dust and resulting in poor efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a negative pressure dust removal packaging conveyor for pumpkin seed production, in order to solve the problem that the existing dust removal structure in the background art is too close to the vibration area, while dust will float and cover other internal structures in the original area, resulting in poor adsorption and low efficiency.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a negative pressure dust removal packaging and conveying machine for pumpkin seed production, including a dust removal box, an efficient dust removal component is provided on the inner side of the dust removal box, and the efficient dust removal component is used to improve the dust removal efficiency; a multi-stage dust suction component is provided on the top right end of the dust removal box, and the multi-stage dust suction component is used to adsorb dust generated in different areas.

[0007] The high-efficiency dust removal component includes an annular frame, which is welded to the top of the left end of the dust removal box. An annular cylinder is embedded in the inner wall of the annular frame, and a worm gear block is provided at the bottom of the annular cylinder. A worm is meshed at the bottom of the worm gear block. A drive shaft is provided in the middle of the annular frame, and a movable screen plate is provided on the outer side of the drive shaft. The outermost end of the movable screen plate contacts the inner wall of the annular frame.

[0008] The multi-stage dust collection assembly includes a dust collection box, which is located at the top right end of the dust collection box. An upper dust collection duct is installed on the left side of the upper end of the dust collection box, and an arc-shaped lower dust collection duct is provided on the left side of the dust collection box. The lower dust collection duct is embedded in the inner side of the annular frame, and filters are provided on the inner side of the ends of the lower dust collection duct and the upper dust collection duct.

[0009] Preferably, a controller is installed on the front of the right end of the dust collector, and a discharge platform is installed on the inner side of the right end of the dust collector.

[0010] Preferably, a feeding box is installed on the top of the annular frame, and the middle of the right side of the feeding box is connected to the upper dust suction duct. The top and lower right sides of the annular frame are provided with through openings, and the upper right side and bottom of the annular frame are provided with notches, which are located outside the worm gear block and the lower dust suction duct.

[0011] Preferably, the input end of the drive shaft is provided with a drive motor, and the drive motor is fixedly connected to the front of the annular frame.

[0012] Preferably, the annular cylinder has through openings on the right side of its top and bottom ends, and the through openings are aligned with the through openings. Bearing sleeves are provided on the outer sides of both ends of the worm gear, and the bearing sleeves are connected to the housing through brackets. An adjusting rod is embedded on the left side of the worm gear, and an adjusting motor is provided at the output end of the adjusting rod. The adjusting motor is fixed to the left side of the dust collector's interior by bolts. Several sets of small holes are provided in the area of ​​the annular cylinder near the through openings, and an air inlet filter is provided on the back side of the lower end of the annular frame.

[0013] Preferably, a vacuum motor is installed on the right side of the dust collection box, and an industrial vacuum cleaner is provided at the output end of the vacuum motor. The industrial vacuum cleaner is located on the right side inside the dust collection box, and an exhaust pipe is provided on the front of the industrial vacuum cleaner.

[0014] Preferably, a fixed filter screen is installed on the inner side of the dust collection box via a bracket, and a collection box is movably arranged on the left side of the lower end of the fixed filter screen. A sealing cover is installed on the front of the collection box, and the sealing cover is fixed to the dust collection box by bolts.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] First, this utility model uses a high-efficiency dust removal component, which works by combining an annular frame and an annular cylinder. After the annular cylinder rotates, the opening area is blocked by the cylinder wall. Pumpkin seeds that enter the annular frame will stay on the inside. Then, the drive motor drives the movable mesh plate to rotate through the drive shaft, thereby pushing the pumpkin seeds down from a height, which further shakes off the surface dust. The shaken dust will always be kept inside the space of the annular frame, and then the dust can be adsorbed by the dust suction device, which can effectively prevent the dust from floating to areas that cannot be adsorbed, thus avoiding the problem of affecting the adsorption efficiency.

[0017] Secondly, this utility model, by installing a multi-stage adsorption component, addresses the issue that existing dust adsorption devices rely entirely on vibration or transmission for dust adsorption. During material feeding, a large amount of dust falls but cannot be directly adsorbed, resulting in decreased adsorption efficiency. By installing an upper and lower dust suction duct on the left side of the dust collection box, one set connecting to the feeding box's channel area and the other to the inner side of the annular frame, the dust accumulated during feeding can be adsorbed once and then adsorbed a second time after falling into the inner side of the annular frame. This multi-stage adsorption component improves efficiency to a certain extent and reduces the time pumpkin seeds spend rotating inside the annular frame. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A negative pressure dust removal packaging conveyor for pumpkin seed production includes a dust removal box 1. The inner side of the dust removal box 1 is provided with a high-efficiency dust removal component, which is used to improve the dust removal efficiency. The top of the right end of the dust removal box 1 is provided with a multi-stage dust suction component, which is used to adsorb dust generated in different areas.

[0025] The high-efficiency dust removal component includes an annular frame 104, which is welded to the top of the left end of the dust collection box 1. An annular cylinder 3 is embedded in the inner wall of the annular frame 104, and a worm gear block 302 is provided at the bottom of the annular cylinder 3. A worm 303 is meshed at the bottom of the worm gear block 302. A drive shaft 202 is provided in the middle of the annular frame 104, and a movable screen plate 2 is provided on the outer side of the drive shaft 202. The outermost end of the movable screen plate 2 contacts the inner wall of the annular frame 104.

[0026] The multi-stage dust collection assembly includes a dust collection box 4, which is located at the top right end of the dust collection box 1. An upper dust collection duct 407 is installed on the left side of the upper end of the dust collection box 1, and an arc-shaped lower dust collection duct 408 is provided on the left side of the dust collection box 1. The lower dust collection duct 408 is embedded in the inner side of the annular frame 104, and filters are provided on the inner side of the ends of the lower dust collection duct 408 and the upper dust collection duct 407.

[0027] The above technical solution involves the use of an annular frame 104 and an annular cylinder 3. After the annular cylinder 3 rotates, it will block the opening 105 area with its cylinder wall. Pumpkin seeds that have entered the annular frame 104 will stay inside. Then, the drive motor 201 will drive the movable mesh plate 2 to rotate through the drive shaft 202, thereby pushing the pumpkin seeds to fall from a height. This will further shake off the dust on the surface, and the shaken dust will always remain inside the space of the annular frame 104. Then, the dust can be adsorbed by the vacuum cleaner, which can effectively prevent the dust from floating to areas that cannot be adsorbed, thus avoiding the problem of affecting the adsorption efficiency.

[0028] Through the above technical solution, by setting an upper suction duct 407 and a lower suction duct 408 on the left side of the dust collection box 4, one set is connected to the channel area of ​​the feeding box 103, and the other set is connected to the inner side of the annular frame 104. During the feeding process, the dust accumulated can be adsorbed once, and after falling into the inner side of the annular frame 104, it will be adsorbed a second time. Through the multi-stage adsorption components, the efficiency can be improved to a certain extent, and the time spent by the pumpkin seeds rotating inside the annular frame 104 can be shortened.

[0029] Specifically, a controller 101 is installed on the front of the right end of the dust collector 1, and a discharge platform 102 is installed on the inner side of the right end of the dust collector 1.

[0030] Through the above technical solution, the controller 101 is used to connect with each group of motors and coordinate control and adjustment, while the discharge platform 102 can export the dust-removed pumpkin seeds for collection and packaging.

[0031] Specifically, a feeding box 103 is installed on the top of the annular frame 104, and the middle of the right side of the feeding box 103 is connected to the upper dust suction duct 407. The top and lower right sides of the annular frame 104 are provided with through openings 105, and the upper right side and bottom of the annular frame 104 are provided with notches, which are located outside the worm gear block 302 and the lower dust suction duct 408.

[0032] Through the above technical solution, the feeding box 103 can pour pumpkin seeds into the inside for feeding, the opening 105 is used to introduce and discharge pumpkin seeds, and the notch is used to avoid affecting the rotation of the annular cylinder 3 and impacting the lower dust suction duct 408 and the worm gear block 302.

[0033] Specifically, the input end of the drive shaft 202 is provided with a drive motor 201, and the drive motor 201 is fixedly connected to the front of the annular frame 104.

[0034] With the above technical solution, the drive motor 201 can drive the drive shaft 202 to rotate when it is powered on, thereby achieving the effect of controlling the movable screen plate 2 to push the material.

[0035] Specifically, the annular cylinder 3 has through-holes 301 on the right side of the top and bottom ends, and the through-holes 301 are aligned with the through-holes 105. Bearing sleeves 304 are provided on the outer sides of both ends of the worm gear 303, and the bearing sleeves 304 are connected to the housing through brackets. An adjusting rod 306 is embedded on the left side of the worm gear 303, and an adjusting motor 305 is provided at the output end of the adjusting rod 306. The adjusting motor 305 is fixed to the left side of the dust collector 1 through bolts. Several sets of small holes are provided in the area of ​​the annular cylinder 3 near the through-holes 301, and an air inlet filter is provided on the back of the lower end of the annular frame 104.

[0036] With the above technical solution, the through-hole 301 corresponds to the through-hole 105. When kept open, pumpkin seeds can normally enter the inner side of the annular frame 104. By controlling the worm gear 303 to rotate the worm wheel block 302 and the annular cylinder 3 along the inner side of the annular frame 104, the annular cylinder 3 can be controlled to close the through-hole 105 area. Then, the movable mesh plate 2 can be used for driving. When the motor 305 is energized, it can drive the adjusting rod 306 to rotate. The adjusting rod 306 is rectangular and embedded in the end of the worm gear 303. Rotation can drive the worm gear 303 to adjust. The small holes and the air inlet filter can ensure that airflow can enter the interior when dust removal and adsorption are performed, thereby pushing the dust into the interior of the dust collection box 4.

[0037] Specifically, a vacuum motor 401 is installed on the right side of the dust collection box 4, and an industrial vacuum cleaner 402 is installed at the output end of the vacuum motor 401. The industrial vacuum cleaner 402 is located on the right side inside the dust collection box 4, and an exhaust pipe 403 is installed on the front of the industrial vacuum cleaner 402.

[0038] Through the above technical solution, when the vacuum motor 401 is powered on, it will drive the impeller inside the industrial vacuum cleaner 402 to rotate, thereby generating suction to draw dust into the dust collection box 4, where it is filtered by a fixed filter screen 404, and the corresponding air will be discharged directly through the exhaust pipe 403.

[0039] Specifically, a fixed filter 404 is installed on the inner side of the dust collection box 4 via a bracket, and a collection box 405 is movably installed on the left side of the lower end of the fixed filter 404. A sealing cover 406 is installed on the front of the collection box 405, and the sealing cover 406 is fixed to the dust collection box 4 with bolts.

[0040] Through the above technical solution, the fixed filter 404 can filter dust, the collection box 405 can collect dust, and the sealing cover 406 can restrict the collection box 405 to the front of the dust collection box 4. After disassembly, it can be cleaned.

[0041] In use, pumpkin seeds are first poured into the inner side of the feeding box 103. During the falling process, the industrial vacuum cleaner 402 will continuously generate suction to adsorb the dust during the falling process. Then, some pumpkin seeds enter the inner side of the annular frame 104. The adjusting motor 305 controls the rotation of the worm gear 303. The worm gear 303 drives the worm wheel block 302 and the annular cylinder 3 to rotate along the inner side of the annular frame 104. The rotation keeps the opening 105 in a blocked state. Then, the drive motor 201 controls the rotation of the movable mesh plate 2, thereby driving the pumpkin seeds to move inside. During the movement, the dust is adsorbed into the dust collection box 4 through the lower suction duct 408. Finally, it is filtered by the fixed filter screen 404. When the adsorption stops, the dust will fall onto the collection box 405. The collection box 405 is restricted by the fastening knob and can be quickly disassembled for internal cleaning.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
